Hi, Do on thing Oppen the Turntable and replace the 5 electrolytic capacitor ( 330mfd 16V,3.3Mfd 25V, two 2.2mfd 25V and 47mfd25v )in the circuit board. Also try to replace the 2 Vriable resistor ( 2K and 5K) in the circuit board of which one is for setting the speed of 33.33 and another for 45 rpm. If you need the service manual then just get in to the following link. You have to wait for some time until you will get a notification that Get the manual. Ajin
If you're lucky, this can just be a dirty/corroded speed control. Try removing the platter and you should see 2 holes lower center of the indented section. In those holes should be the coarse speed controls. These really set the range of the fine speed controls we play with on the outside. Use a good commercial contact cleaner and spray these babys. Gently move them a bit counter clockwise and clockwise, spray again, then return to about where they started.
If that doesn't help, you either have a motor issue or the controller board has a problem - no easy fix there.
You need to check that the signal is getting to the amp. This can be done by removing the wires off the cartridge for the left and right channels. With the amp on touch the ends of the wires. If you hear a buzz the signal is getting to the amp and the cartridge is dead, but if you hear nothing and if the wiring is as you say good. Then the pre-amp in your amp for the cartridge has failed. This pre-amp will only affect the record deck and no other functions. If it has gone you can trace the wires from the sockets to it. Sometimes it will be on a seperate PC board. It's often a single IC that has failed. If you can replace it yourself be careful with the new one as these are often static sensitive chips.
PS the phono scokets on the amp sometimes buzz if you pull the plugs in & out!
hi aris tomas...1st check the fuse inside the turntable..then if its ok go to the main board ..check the zener diode (D3) and the transistor Q3 and Q2...the fidbk me wat hapen , if possible if you can chance it replace it..u
